ISO Disc Hubs

Months of design and testing went into our ISO disc hubset. During the development process, we adapted our machines to use larger bar stock when we make the hub shells. This manufacturing improvement allowed us to increase the spoke flange diameter significantly. A larger spoke flange spreads the spoke holes away from each other. Also, you can use shorter spokes to build a more durable, stiffer and stronger wheel.

Make no mistake, these are not "disposable" parts. There are a lot of super light hubs out there, but will they still be working in 2 years? How about 5? If you ride a lot, 5 years is a lot of panic stops, high speed feathering and braking bumps. Like all of our other hubs, these carry a 5 year warranty. It is easy to make a really light hub, not so easy to make one that you can sell with confidence and back that up for 5 full years. Who else does this but King?

* Compatible with the new Shimano 11-speed mtb system.

Ceramic Bearings - Made in-houseWe make our own ceramic bearings and we build them to the same exacting standards as our classic, time-tested stainless steel ball model. Pairing the corrosion resistance of ceramic balls with our proven sealing system allows for greater flexibility with greasing options. We build our ceramic bearing ISO hubs with a very small amount of silicone-based lube for a system with very low drag. Take advantage of our user-serviceable bearings and run minimal lubrication for the ultimate in race-day performance.

Stainless Steel Bearings - Made in-house
The ISO hubsets also have the option of stainless steel sealed bearings. As with every King bearing, these bearings are made in-house in Portland, Oregon and individually hand-checked for precision and smoothness.
